BABY-JUMPER.

SPECIFICATION forming part of Letters Patent No. 430,324, dated. June17, 1890.

Application filed March 1, 1890.

Serial No. 342,289. (No model.)

To aZZ whom it may concern.-

Be it known that I, DAVID C. SHEELEY, a citizen of the United States,residing at Wayne'sborough, in the county of Franklin and State ofPennsylvania, have invented certain new and useful Improvements inBaby-Jumpers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention is an improvement in baby jumpers; and it consists incertain novel features of construction and arrangement of parts, whichare hereinafter fully described and claimed.

I have illustrated one form in which I have contemplated embodying myinvention in the accompanying drawings, in which-- Figure 1 is aperspective view of my improved baby-jumper, the supporting-cords beingbroken away. Fig. 2 is a longitudinal section of the same, the partsbeing extended into a horizontal plane. Figs. 3, 4, and 5 are detailviews of parts of the construction.

The frame of my improved baby-jumper consists of a seat portion and aback portion pivotally connected together and adapted to be adjustedwith respect to each other. The seat portion consists of the side piecesA A, connected together at their forward extremities by the cross-bar a.The side pieces B B of the back portion are pivotally connected to thepieces A A at b b, and the said pieces B B are connected together attheir free ends by the cross-bar b. The side pieces B are each providedwit-h a segmental portion b which overlaps the adjacent side piece Awhen the device is in the position shown in Fig. 1, arranged in the formof a chair. The curved edges of the portions b are concentric with thepoint of pivoting b, and the side piecesA A are provided with guides ata, secured thereto, which engage the said seg- 45 mental portions andguide them when the parts are moved with respect to each other andprevent them from springing apart.

The parts B B are also provided with pins or straps 17 b which are soplaced as to engage the guides a a andlimit the backward movement of theback portion.

In order to adjust the parts with respect to each other to allow theback to be tilted rearwardly and extended into the plane of the seatportion when the device is desired to be used as a bed, I provide theside pieces A A with one or more holes or recesses a a arrangedconcentrically with the point of pivoting b, and provide the parts B Bwith springactuated pawls or bolts b b, adapted to en- 6.0 gage thesame. The pawls 11 1) are mounted in sockets b b and provided withsprings b" in any preferred manner, which tend to hold the said pawls inengagement with the side piece B. By this means the pawls may be drawnout and the parts adjusted to thedeslred positi0n,where they will beheld by the engagement of the pawls with the proper holes or recesses.The side pieces A A are also preferably provided with segmental portionsa which conform to the shape of the overlapping segmental portions ofthe side pieces B B when the parts are arranged as a bed, as best seenin Fig. 2.

In pivoting the side pieces A and Btogether I prefer to employ theconstruction shown in Fig. 4. This construction consists of theface-plate 19 having a downwardly-extending hook portion If. This plateis also provided with the pivot b", which passes through the parts A andB and engages a plate or washer 19 on the outside of the frame. Theseparts are secured together by riveting, as shown, or by any otherpreferred means, such as a screw or nut. The plate b is also 5 providedwith a rearwardlyextending arm I). The bottom and back of the device arepreferably formed from a continuous piece of flexible material C, whichis secured at each end to the cross-bars a and b, as shown 9 in Fig. 2.The material C is secured at opposite edges to the retaining projectionsb adjacent to the point of pivoting b, by means of a rivet,screw, or other preferred means. By this construction I dispense with acentral cross-bar and yet secure the flexible material from being drawnaway from the sides of the frame, and also provide an intermediatesupport for the said material. I also provide the device with af0otrest, as shown in Fig. 2. 1

This consists of the frame D formed, preferably, of stiff wire suitablycovered with flexible material, and provided at its free ends with theslotted yokes d, which engage the cross-bar a. The yokes cl are alsoprovided each with a hook or projection 61', adapted to engage one ormore pins d d 011 a plate (1 secured to the side piece A. Then it isdesired to have the foot-rest form a continuation of the seat portion,the hook cl is made to engage the pin orlug d as shown in Fig. 2, andthis will customarily be the manner of using the foot-rest. WVhen thedevice is extended to form a bed, frame D is desired to serve as a rest,and when the parts are arranged as a chair the hooks d are made toengage the pins 61 and the foot-rest will then occupy an inclinedposition, as shown in dotted lines, Fig. 1, WVhen not in use, thefoot-rest will be disengaged from the pins d (1 folded beneath the seatportion, and placed in engagement with the hooks b of the hinge-casting,as shown in Figs. 2 and 4. The slotted yokes d will allow for thelongitudinal movement of the frame D in changing its positions withoutbecoming disengaged from the cross-bar a.

The j umper-frame, hereinbefore described, is supported from somesuitable point by means of cords or ropes e e, secured to the free endsof the seat portion and to the free end of the back portion, each cordextending from one point to the other, as clearly shown in Fig. 2. Thesecords engage a frictionblock E, which consists of wood or other suitablematerial, provided with four parallel passages, and each cord passesupward through one passage and down through another, the edges of theapertures adjacent to their up per extremities being smoothed to preventwear of the cords. The block E is also provided with a swivel-hook E forsupporting the same and allowing the device to be rotated, if desired,on the said swivel. When the block is suspended to some rigid support,it will be seen that the frame of the jumper can be instantly placed inany desired position, the cords sliding through the apertures in theblock to permit the said adjustment, and when properly adjusted thecords will be held by frictional engagement from being moved in any wayby the movement of the frame or the occupant. I also provide the cords ec with a stop to engage the said block and limit the movement of thejumper, as desired. I have found by experience that there is nonecessity for a stop to limit the backward movement of the cords; but Iprovide the cords in rear of the block with a stop to limit theirforward movement and prevent the occupant from being accidentally thrownout-forward by carelessness in adjusting the position of the frame. Thisstop consists of a coupling 6 which connects the cords e e at thatpoint, and is so constructed as to engage the under face of the block asthe cords are drawn through the same and limit the movement of thecords, as described. By attaching the said stop to both cords I forcethe cords to move together and evenly, thereby avoiding any unevenadjustment and consequent twisting of the frame by having one sidehigher at one end than the opposite side.

What I claim, and desire to secure by Letters Patent, isr 1. Ababy-jumper consisting of a seat and a back portion hinged or pivotedtogether, cords extending from the free end of the seat portion to thefree end of the back portion, and a supporting device frictionallyengaging said cords intermediate their ends, substantially as described.

2. The combination, with a baby-jumper consisting of a seat and a backportion hinged together, of cords extending from the free end of theseat portion to the free end of the back port-ion, a supporting devicefrictionally engaging said cords intermediate their ends, and a stopsecured to said cords,substantially as described.

3. A baby-jumper consisting of a seat and a back portion pivotedtogether, said parts having overlapping curved portions concentric withthe point of pivoting, a guiding device upon one of said curved portionsand en gaging the other, a spring retaining-bolt, and supporting meansconnected to the free ends of the seat and back portions, substantiallyas described.

4. A baby-jumper consisting of a seat and a back portion pivotedtogether, the said seat and back being composed of frames consisting ofside pieces joined by a cross-bar at their free ends, the two framesbeing pivoted together by short pivots connecting the side pieces of theframes, flexible material extending from the cross-bar of one frame tothat of the other and attached to the frames in line with the pivots, adevice for retaining the frames at the desired angle of adjustment inrelation to each other, and supporting means connected to the free endsof the seat and back, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID C. SHEELEY.
